Review: Awesome Datalogger - I bought this Data logger to log temps for Freezers, Ambient Car Temp (in the summer) and various other applications. Its very easy to use, Windows Interface works without complication for downloading and graphing Temp, Dew Point, Humidity. Software only works in Windows, but will work under VMWare Fusion (or Bootcamp / Parallels). This unit was bought used and but was in brand new condition (it appeared it had never been used) - very happy with this transaction and product. Only drawback I saw was when you download the data, it quits logging new data. You have to reset the logger (and clear its previous logs) before starting a new log. You can't "spot check" the temp and then return it to keep collecting data... other than that, its an awesome product.

The unit is well built and comes with several useful accessories. From the front panel you can see current/max/min temp & humidity. You need to connect it to a PC via USB to set the unit's date, time, and logging options. The software installed fine on my Win 7 64-bit PC. I downloaded the latest version from the Extech website. The software works surprisingly well. I was able to quickly set up a logging schedule, set the time on the unit, and switch to Fahrenheit. Many logging options are available, from 1 sample per second (max 4 hours, 32 minutes) to one sample every 24 hours, and everything in between. I used one sample per minute which will last 11 days 8 hours. You can have the unit stop logging after it collected the max # of sample, or overwrite the oldest data. It records temp & humidity simultaneously. After a week of of logging, I connected the unit to my PC and was able to download the data quickly and display it in graph or spreadsheet form. If you export the data to a file, it is a tab separated file, and can be opened in a spreadsheet. Each timestamped (m/d/y h:m:s) temp & RH reading will be in the file. The graphic display can't be saved by the program, but you can screen capture it. Data can also be stored in a propriety format for reading into the software later. On the not-so-great side, You can't do much from the front panel, like change from Celsius (factory default) to Fahrenheit or setup logging, or view previous logs. User manual is sparse (-1 star) and a little helpful. If you're not handy with a PC, this unit may not be for you. The front panel display is a bit confusing, there's some data there I don't understand. No backlight. The battery is one of those expensive non-rechargeable camera batteries, a standard 9V or AA, AA would have been nicer. There are two tiny (easy to lose) screws holding the battery cover in place, but the screws go into a metal sockets, not plastic - thank you Extech for that. The battery cover also looks to be environmentally sealed. Overall, I'm very happy with my purchase and recommend the RHT20. ## Frequently Bought Together - EXTECH Instruments RHT10 Humidity and Temperature USB Datalogger - Extech 445580 Humidity and Temperature Pen Sized Meter with Pocket Clip - Extech RH300-CAL Humidity Calibration Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/6646298-rht10-humidity-and-temperature-usb-datalogger-with-16-000-data](https://www.desertcart.uy/products/6646298-rht10-humidity-and-temperature-usb-datalogger-with-16-000-data) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-25*
